Sierra Wireless MC7304 - Setup?
xevian last edited by
I've just built myself a new pfSense box, and wanted to get a 3g/4g failover working… I've done a fair bit of search but found nothing conclusive on getting the MC7304 to work.
It's being detected be not giving any serial interfaces. I suspect I need to change it's mode somehow (I remember using usb_modeswitch on Linux with an older USB modem) but not sure on this card.
If anyone has any insights on getting the card to work!

I don't have exactly the same modem myself, but I suppose it will not work with pfSense:
- there is no support for MBIM or QMI
- some Sierra devices expose only single serial modem interface while pfSense would like to see 2 ports, one for PPP and another for the control
Anyway, you can try. Please show the output of AT!UDUSBCOMP=? and AT!UDUSBCOMP?
Don't forget to unlock commands with AT!ENTERCND="A710" (assuming you have a com port exposed by the card)
just noticed "not giving any serial interfaces". It's probably not the best approach, but you may need to use Windows or Linux machine to make the change. There are some recipes on Internet, just google for "mc7304 enable ports"

Actually MBIM is what it needs. The MC73xx family is all the same.

Notice udusbcomp=8 and that is MBIM +GPS+AT Console+DM
So AndrewZ is absolutely right is that it needs switching from QMI mode for the serial ports to show up in FreeBSD/pfSense.
You can use a Linux LiveCD and minicom into the modem and do the switch with at!udusbcomp=8.
When you switch it to composition 8 you are enabling the AT port which is what pfSense can use. You get an MBIM port too but there is no MBIM support in FreeBSD yet.
It would work equally well in compositions 6, 7 or 8 but not in 9 which is probably what it was set by default.
if you choose 14 or 19 then you get two USB config indexes and can choose between them.
